v7a: barebox: version bump v2021.04.0 → v2021.05.0

Updating to v2021.05.0 lets us drop the single patch we have,
as it went upstream in revised form.

Kconfig changes are those produced by oldconfig. One notable
new option is CONFIG_DEFAULT_ENVIRONMENT_GENERIC_NEW_IKCONFIG,
which allows barebox to embed its configuration as /env/data/config
analogously to /proc/config.gz, which we already enable for Linux.
This is not enabled here, but might be something we want to use
eventually.

-Subject: [PATCH master] usb: dwc2: increase timeout for waiting on host mode
-
-Commit 26459ab7803a ("usb: dwc2: Rework wait for host mode during
-core reset") effectively reduced the timeout on switch to host mode
-from 200ms to 110 us, which is insufficient for the IP on the Raspberry
-Pi 3b, leading to:
-
-  dwc2 3f980000.usb@7e980000.of: dwc2_wait_for_mode: Couldn't set host mode
-
-and an unusable USB (and Ethernet) after.
-
-Bump up the timeout to 200ms and help future debugging by logging how
-much time it actually took. For the Raspberry 3b I got a value of 49ms.
-
-Note that this is also called from dwc2_force_mode, so worst case is
-that a stuck IP delays barebox startup by 200ms.
-An error message would alert to this fact, so it can be corrected.
-
